This was really fun to grow! I am in zone 10 here in Hawaii. We get day time temps of mid 80’s and night time temps of mid 60’s. I started the seeds in April and now they are starting to bloom. I’m excited to start more seeds and plant them all over my garden.

Started seed indoors April 2023 and transplanted out into the garden in June (Zone 5). They did not bloom their first year but grew nice strong leaves. This year, 2024, I got a first flush of booms in June and then a second more vigorous flush of blooms mid-Summer. They are still going strong and will most likely have blooms through fall. The only thing is I’m not sure how much of a “double” flower I’m seeing and they just look like a normal yellow coreopsis flower. Oh well still bright and cheery! Thanks BI!

I live on alvar land in the summer (very thin layer of alkaline soil over the limestone bedrock). A reseeding coreopsis is one of the few things that grows well here. Also, the columbines, nigella, and verbascum (zone 4-5). In the winter I go to zone 7B Maryland and can plant anything in the acidic, sandy loam. I love the instructional packaging.
